At which point on the diagram do convection currents occur to drive plate movement?

I don't see a diagram but if you are talking about tectonic plates then it would be the magma under the earth that the crust sits on

Explanation:

The distance around a circle is equivalent to a circumference and calculated as 2•pi•R where R is the radius. The time for one revolution around the circle is referred to as the period and denoted by the symbol T. Thus the average speed of an object in circular motion is given by the expression 2•pi•R / T.

Step-by-step explanation:

It is a vector quantity. For example, if a body moves along a circle of radius r and covers half the circumference, then displacement is given by s=2r. In one-dimensional motion displacement of the object will be the shortest distance between final and initial point.
